사전정보는 클러스터링 성능을 유도할 수 있는 요인이지만, 활용 방법에 따라 차이는 발생한다. 특히, 사전정보를 초기 중심으로 활용할 때, 사전정보 간 유사도에 대해 고려하는 것이 필요하다. 레이블이 같더라도 낮은 유사도를 갖는 사전정보로 인해 초기 중심 설정 시 문제가 발생할 수 있기 때문에, 이들을 구분하여 활용하는 방법이 필요하다. 따라서 본 논문은 낮은 유사도를 갖는 사전정보를 구분하여 문제를 해결하는 방법을 제시한다. 또한 유사도에 의해 구분된 사전정보는 다양하게 활용함으로써 생성되는 다양한 클러스터링 결과를 연관규칙에 기반하여 앙상블 함으로써 통합된 하나의 분석 결과를 도출하여 클러스터링 분석 성능을 더욱 개선시킬 수 있다.

This study was carried out to investigate the children's knowledge, attitudes and practices of food safety. A total of 355 data were collected from elementary school students. The concern of food safety was moderate in 5 point Likert scale and relatively high correlated with food safety knowledge(r=0.571) and education(r=0.534). The experience and knowledge of terminology on food safety were estimated. The level of food safety was classified into 5 groups and the consideration of food purchase was classified into 3 groups by factor analysis. A few children were aware of the food safety knowledge and could hardly understood English terminology. And the food safety practices were surveyed, and most of children checked with expiration dates and packaging conditions of food. Personal hygiene practice of children was significantly affected by gender, self hygiene evaluation and the knowledge level of food safety. Providing more food safety information affects personal hygiene and the practices of food purchase, so educational programs on food safety for children were required.

This study aims to explore factors of Assimilation Gap(AG) which is proposed and illustrated by Fichman and Kemerer(1997). AG is defined as the time delay between adoption and deployment and mainly studied at the organizational level. This study derives the factor affecting AG through a review of technology acceptance models and agency theory. The research model consists of three groups of independent variables(IT knowledge burden, Individual characteristics, and organization characteristics) and a moderator, which is goal incongruence. Using multiple regression analyses, four groups of hypotheses are tested with data of 221 knowledge workers from various organizations through e-mail survey. The result shows that radicalness(a dimension of knowledge burden), personal innovativeness, self-efficacy, and organizational support are statistically significant factors while complexity, experience, and perceived critical mass are not supported. The moderator effects of goal incongruence are found in personal innovativeness and organizational support. The results of this study demonstrate that agency theory is a useful perspective to deal with AG, especially in radical innovation. In addition, IT practitioners should consider not only user training but also incentives and possible organizational controls in implementing a new information technology.

As personal data breach reared up as a problem domestically and globally, organizations appointing chief privacy officers (CPOs) are increasing. Related Korean laws, 'Personal Data Protection Act' and 'the Act on Promotion of Information and Communication Network Utilization and Information Protection, etc.' require personal data processing organizations to appoint CPOs. Research on the characteristics and role of CPO is called for because of the importance of CPO being emphasized. There are many researches on top management's role and their impact on organizational performance using the Upper Echelon theory. This study investigates what influence the characteristics of CPO gives on the organizational privacy performance. CPO's definition varies depending on industry, organization size, required responsibility and power. This study defines CPO as 'a person who takes responsibility for all the duties on handling the organization's privacy,' This research assumes that CPO characteristics such as role, personality and background knowledge have an influence on the organizational privacy performance. This study applies the part relevant to the upper echelon's characteristics and performance of the executives (CEOs, CIOs etc.) for CPO. First, following Mintzberg and other managerial role classification, information, strategic, and diplomacy roles are defined as the role of CPO. Second, the "Big Five" taxonomy on individual's personality was suggested in 1990. Among these five personalities, extraversion and conscientiousness are drawn as the personality characteristics of CPO. Third, advance study suggests complex knowledge of technology, law and business is necessary for CPO. Technical, legal, and business background knowledge are drawn as the background knowledge of CPO. To test this model empirically, 120 samples of data collected from CPOs of domestic organizations are used. Factor analysis is carried out and convergent validity and discriminant validity were verified using SPSS and Smart PLS, and the causal relationships between the CPO's role, personality, background knowledge and the organizational privacy performance are analyzed as well. The result of the analysis shows that CPO's diplomacy role and strategic role have significant impacts on organizational privacy performance. This reveals that CPO's active communication with other organizations is needed. Differentiated privacy policy or strategy of organizations is also important. Legal background knowledge and technical background knowledge were also found to be significant determinants to organizational privacy performance. In addition, CPOs conscientiousness has a positive impact on organizational privacy performance. The practical implication of this study is as follows: First, the research can be a yardstick for judgment when companies select CPOs and vest authority in them. Second, not only companies but also CPOs can judge what ability they should concentrate on for development of their career relevant to their job through results of this research. Cultural social value, citizen's consensus on the right to privacy, expected CPO's role will change in process of time. In future study, long-term time-series analysis based research can reveal these changes and can also offer practical implications for government and private organization's policy making on information privacy.

Software project planning is usually represented by a project activity network that is composed of stages of tasks to be done and precedence restrictions among them. The project network is very complex and its construction requires a vast amount of field knowledge and experience. So this study proposes a case-based reasoning approach that can generate the project network automatically based on the past cases and modification knowledge. For the case indexing, we have adopted 17 factors, each with a few alternative values. A special structure of this problem is that the modification effort can be identified by each factor independently. Thus it is manageable to identify 85 primitive modification actions(add and delete activities) and estimate its modification efforts in advance. A specific case requires a combination of primitive modifications. Based on the modification effort knowledge, we have adopted the Least Modification approach as a metric of similarity between a new project and past cases. Using the Least Modification approach and modification knowledge base, we can automatically generate the project network. To validate the performance of Least Modification approach, we have compared its performance with an ordinary minimal distance approach for 21 test cases. The experiment showed that the Least Modification approach could reduce the modification effort significantly.

Today's firms are experiencing severe competition and lots of change under uncertainty of the future. In order to survive in rapidly changing environment, companies have steadily adopted information technology(IT) environment. The advancement of information technology allows people to access information and knowledge resources without the limitation of time and location through internet. Many organizations have developed their own information systems not only for internal efficiency but also for effectiveness of external customer services. This study is intended to provide a theoretical framework of information and knowledge and their relationship, that the infusion of powerful information networks into business environments is beginning to have a profound a significant difference of the nature between information satisfaction and accounting information system(AIS) in the business activity. This paper is to maximize the efficiency of university libraries human resources management by determining the followings the relationship between the level of information technology implement and the job satisfaction of the librarian, the main factors that affect job satisfaction. Questionnaire was sent to 120 companies from 20 corporations chosen by random sampling and the methods of ANOVA, T-test, and correlation analysis were used. The results of the analysis are as follows; 1) There is a unsignificant difference in the level of information satisfaction by accounting information system and the motivation factor according to the level of implementation of IT. 2) There is a relatively high in a significant difference in information satisfaction by the level of net income. 3) There is high a significant difference is shown in the accounting years while implementing the IT and information satisfaction.

Since social network service (SNS) has been widely used as a effective way for people to connect and communication with each other, the use of corporate SNS account also has increased. However, compared to a private SNS account, only few people have a continuous relationship with their corporate SNS account because the use of corporate SNS account tends to be one-time and temporary activity whenever the users just need events and information. Given the psychological side effects of using SNS, the relative lack of empirical studies on the impacts of emotional factor in SNS prevents the deeper understanding of the intention to continuous using corporate SNS account. Therefore, this study aims to explore key determinants of the intension to continuous using the corporate SNS account from a habit and emotional perspective. To bridge research gap, we attempt to divide emotional factor into the following 5 factors based on Mehrabian and Russell model (1974): intimacy, enjoyment (positive factor), privacy concern, anxiety (negative factor), arousal (arousal factor) and (dominant factor). The basic model is proposed to explore the effects of habit and emotional factors on the intension to continuous using the corporate SNS account. We then examine how the effects of habit and emotional factors differ depending on social media types (e.g., facebook and twitter). The results indicates that habit is related to emotional factors, and each emotional factor differently influences the intension to continuous using the corporate SNS account. The results also confirm that the effects of the habit and emotional factors on the intension to continuous using the corporate SNS account differ according to social media types. This study provides practical and useful guidance and the strategic marketing insight for managers in maintaining and improving the intension to continuous using the corporate SNS account.

With the widespread use of smartphones and the development of information technology, an online service called SNS(social network service) has emerged, and as an increasing number of people began to use SNS, extensive research has been conducted on SNS. SNS is an important factor for adolescents who are developing social skills that help them to adapt to the society, and for adults who are stepping into the society. The present study investigates the effects of information search, self-disclosure, interaction, and playfulness, all of which are motivational factors for SNS use, on flow in SNS, and empirically analyzes the degree of these variables influence according to flow in SNS and individual's personal nature(extrovert, introvert). The analysis results showed that information search, self-disclosure, interaction, and playfulness were positively correlated with flow in SNS, and flow in SNS was positively correlated with social skills. The degree of influence varied depending on the individual's personal nature(extrovert, introvert). These findings may provide important insights for researchers studying SNS, SNS managers, and company officials using SNS.
